Formulas:
L2 bandwidth [MBytes/s]   = 1.0E-06*(DATA_CACHE_REFILLS_L2_ALL+DATA_CACHE_EVICTED_ALL)*64/time
L2 data volume [GBytes]   = 1.0E-09*(DATA_CACHE_REFILLS_L2_ALL+DATA_CACHE_EVICTED_ALL)*64
L2 refill bandwidth [MBytes/s]   = 1.0E-06*DATA_CACHE_REFILLS_L2_ALL*64/time
L2 evict [MBytes/s]   = 1.0E-06*DATA_CACHE_EVICTED_ALL*64/time
-
Profiling group to measure L2 cache bandwidth. The bandwidth is
computed by the number of cache line loaded from L2 to L1 and the
number of modified cache lines evicted from the L1.
Note that this bandwidth also includes data transfers due to a
write allocate load on a store miss in L1 and copy back transfers if
originated from L2.
